The PP dual color sheet production line is a modern production line used to manufacture PP plastic sheets with a dual color appearance. It adopts advanced extrusion technology and special dyeing process to produce high-quality dual color PP sheets.
Firstly, the PP particles of the raw material are fed into the extruder. In the extruder, PP particles are heated and extruded under high pressure, and the PP is melted and extruded into sheet shape through screw rotation. The temperature, pressure, and speed of the extruder can be adjusted as needed to ensure that the quality and thickness of the sheet meet the requirements.
Next, the sheet enters the dyeing equipment for dual color dyeing treatment. This step uses special dyes and dyes to form two different colored layers on the surface of the sheet. Usually, dyes undergo chemical reactions with the surface of the sheet to ensure the stability and adhesion of the dyeing layer. The color and distribution of dyeing can be adjusted according to customer requirements and market demand.
Subsequently, the sheet is rapidly cooled through a cooling device to ensure the solidification and stability of the dye layer. The cooling process can control the temperature and hardness of the sheet material to better cope with subsequent processing and usage environments.
Finally, after cutting and coiling, the PP dual color sheet production line can cut the produced sheet according to different sizes and lengths, and roll it into a drum form, facilitating subsequent packaging and transportation.
The production line is also equipped with an automated control system that can monitor and adjust parameters in real-time during the production process to improve production efficiency and product quality. The design and process flow of the PP dual color sheet production line are committed to achieving efficient, stable, and attractive dual color sheet production, meeting the needs of various application fields, such as home decoration, automotive interior, daily necessities, etc.
